Thermal demagnetization has successfully isolated high unblocking temperature characteristic directions from paleomagnetic samples of Lower and Middle Cretaceous redbed formations from eastern Qiangtang Terrane, Tibet. The tilt-corrected mean direction for the Lower Cretaceous is D/I=57.7¿/50.2¿ with α95=10.9¿ and N=12 sites, and that for the Middle Cretaceous is D/I=39.7¿/51.6¿ with α95=8.5¿ and N=11 sites. Both formations pass the fold test, and the latter possesses two polarities. The magnetization predates the Eocene and was probably acquired during Cretaceous time. Comparison of the mean directions with expected directions from the stable interior of Eurasia indicates significant clockwise rotation but little paleolatitudinal change for the sampling area. Deformation and rotation of these rocks are presumably related to the collision of India with Asia and its subsequent northward indentation into Asia. Existing paleomagnetic data from Tibet and its environs seems to be compatible with a crustal shortening/thickening model (Dewey et al., 1988) in that the confidential crust directly north of the Indian indenter was substantially shortened north-south, whereas in the vicinity of the Western and Eastern Syntaxes, latitudinal displacement was minimal but tectonic rotation was very important. More data are needed to further differentiate between this model and the lateral eastward crustal extrusion model (Molnar and Tapponier, 1975). ¿ American Geophysical Union 1992
